Sighting in Sumantra 22 cal

[Blueswaite]

Was not getting consistency on my groups so I had power at half turned it down 3 clicks and got 12 shot groups I could cover with a Quarter That was at 35 yards with H&N Barracuda Match 21.14 Grain. Very happy with results.
Still need to get a chrony but learning the power wheel and understanding it. I would guess the gun at half power was a little to hot.
Thanks

They are very powerful guns indeed. 21grain is quite light for any of the settings above the low settings in my opinion. I really like the 28gr Seneca pellets and the JSB 33.95gr for higher settings. Glad it is performing well and you found the right sweet spot!

Hard Air did a review on Sumantra 22 and H&N 21.14 Grains was one and on lowest Power they got 1111 FPS and almost 50 fpe. That’s kind of what gave me the idea to drop the power.
I really didn’t think 3 clicks would do much guess the power wheel works better than I thought.
Thanks

I'd give the 28g & 32g Senecas (Eun Jin), a try. The Korean pellets seem to work very well in Korean airguns.

Drop the power level some more and your groups might improve further!

I’ll go Down a few more clicks if it isn’t any better I can take it back. Are the Seneca 28 grain going to be over kill for squirrels.
I have a UTG 3x9x40 AO Hunter Scope On it Set At 6 power were I leave it. We’re do you guys set your power. My max range for now is 40 yards.
Thanks

Not at all. The 28g Senecas kill squirrels very well.
